shara ... don't be embarrassed . this has also happened to technics kn players ... I just read the post and was going to respond when I saw the problem had been resolved ... as for your kb cover... did your 9k come in a box? .. if so, and you still have it, you could probably cut one of the wide panels off it and use what's left to put over the kb when you're not using it ... I got the idea a number of years ago when I bought a Peavey head and they did not make a cover for it ... The box it came in was pretty sturdy cardboard, so I cut the top flaps off, turned it upside down, cut a slot for the handle on the head, covered the whole thing with black duct tape, and that's been the cover for about 10 years...
Good luck ...
